A: Mmm hmm. In 1982, John Kenneth Galbraith explained "supply-side theory" as "what an older and less elegant generation called the horse-and-sparrow theory: If you feed the horse enough oats, some will pass through to the road for the sparrows." So, how's that been working for the sparrows? "The mainstream economic evidence is that the bulk of corporate tax cuts go exactly to whom you would expect — which is wealthy investors and executives," said Chye-Ching Huang, deputy director of federal tax policy at the left-leaning Center on Budget and Policy Priorities. But, wouldn't companies use money from tax cuts to expand their businesses and hire more people? Maybe during a recession, but not when corporate borrowing rates are so low, like they are now. So, what to do? How about we follow Galbraith's advice: "Let us cease to think of economic policy in terms of liberalism or conservatism and retreat to common sense."
